NRT-250

The NRT-250 is a versatile Polarization Tracker designed for OEM integration and sub-system.

Overview

The NRT-250 uses the same integrated-optic Lithium Niobate (LiNbO3) waveguide polarization-controller device for super-fast polarization response as its lab unit cousin the NRT-2500. The NRT-250’s Tracker is FPGA driven making it even faster than the NRT-2500.

Tracker

Fast Robust and Endless Polarization NRT’s unique tracking algorithm enables virtually perfect SOP tracking with no dropouts or ‘glitches’ for your new applications and prototypes. The NRT-2500’s open architecture allows you to optimize the performance for your specific application:

Create a unique error signal from four A/D converter inputs,

Optimize algorithm parameters with Tracker’s ‘Optimizer’ program.

New Ridge has leveraged many years of experience in the Tracker. And has packaged it all together for you. The Tracker’s technology is so robust, it has been incorporated in multiple systems and qualified for network deployment at a number of carriers worldwide.
